I use an extra call to the 3rd party server, and its response content type changes from time to time.
For one connection I get application/json (that is what I expect) but another time I get the application/octet-stream with the same request. The url is always same and expected response size isn't big.
Let's say I call https://sideapp.co.uk/symbolname/1/hour/date1/date2
How can it be explained? I don't know which language they use on there backend side. I've only found the one possible explanation for Java here: Why is my controller sending the content type "application/octet-stream"?
From my side I use Flux WebClient for connection but I get the same behavior with pure browser call as well.
